Python 使用布局管理器管理不同大小的不同小部件

我想开发一个应用程序，它由不同大小的小部件组成，如图所示。当我使用一个特定的布局，例如网格布局时，窗口小部件在窗口中被组织成相等的部分。但我希望它们显示为不同的大小

示例代码（.py）在这里。我想降低QGroupBox的高度

解决方案是设置拉伸系数，在您的情况下，您应该单击顶层下方的QFrame，并在

0,1

处查找QGridLayout的layoutRowStrecth部分：

请提供一个示例，您可以告诉我使用qt designer设计如图所示窗口的一些基本步骤吗？您说您已经使用了QGridLayout，并且您在拉伸方面遇到了问题，因此如果您可以提供该代码，那么我们可能会帮助您建立这些拉伸。我添加了一个示例代码，我想降低QGroupBox你能分享一下.ui吗？因此可以很容易地修改它
